gnu-efi Code

EFI_PXE_BASE_CODE was redefined in the early commit(*) to match the
definition in EDK2. However, EFI_PXE_BASE_CODE wasn't declared
correctly. Since EFI_PXE_BASE_CODE_PROTOCOL is already an alias of
"struct _EFI_PXE_BASE_CODE_PROTOCOL", the additional struct in front of
EFI_PXE_BASE_CODE_PROTOCOL actually confused the compiler and caused
build fail. Remove the redundant struct to avoid confusion.
